Meanwhile, Ether.fi will migrate its crypto card to the OP Mainnet.

Coinbase-supported L2 solution Base has announced its transition from the Optimism technology stack to its own unified architecture.

Currently, the code for key components (such as the sequencer) is spread across various teams and repositories, complicating system maintenance. The new unified base/base solution, utilizing open components like Reth, will simplify and enhance the architecture.

Every network update will be released as a single official binary file for Base. The project will remain open, with public specifications allowing the community to create alternative clients.

According to the developers, this transition will reduce reliance on third-party providers and accelerate the implementation of new features. The team aims to execute six minor hard forks per year instead of the current three.

The rollout of the new architecture will occur in four phases. In the coming months, node operators will need to switch to the new Base client, which will be the channel for all official updates.

"In the coming months, around 70,000 active cards, 300,000 accounts, and user assets worth millions will transition to the Optimism ecosystem," the developers stated.

Launched in 2024, the Ether.fi Cash project offers a non-custodial method for purchasing with stablecoins. Users can also utilize eETH as collateral.

The cards are accepted wherever Visa operates, becoming the dominant cryptocurrency payment method, accounting for nearly half of all transactions in this segment.

Ether.fi explained its choice of Optimism due to access to extensive liquidity for swaps, a greater variety of assets for deposits and withdrawals, and the ability to pay gas fees.

"For end users, the transition will be seamless. Optimism has a successful track record of handling large migrations in the past and a well-established safe process to avoid disruptions," Ether.fi assured.

In February, Ethereum co-founder Vitalik Buterin stated that the original concept of Layer 2 solutions has become outdated. His comments sparked mixed reactions within the community.
